F5 LTM hardware failover Vs network Failover

@Mike, From where did you get the information in regards to which failover method has precedence? That's actually the opposite. https://support.f5.com/kb/en-us/solutions/public/2000/300/sol2397.html

(My point of view) When you configure HA, it's best to never use the hardwired failover, and only stick to network failover. F5 recommends to configure both, but I think that having a superior HA solution suppressed by something based on very low-level voltage heartbeats does no good to reliability.
